DETAILED DESCRIPTION

[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 3As shown, a kitchen waste crushing device 10 includes: a driving component 11, two moving knife groups 12 and a mounting frame 13. The driving component 11 is mounted on the mounting frame 13. The mounting frame 13 forms a crushing space 131. The two moving knife groups 12 are mounted in the crushing space 131 of the mounting frame 13. The driving component 11 drives the two moving knife groups 12 to crush the kitchen waste. The crushed garbage is decomposed by microorganisms and eventually becomes organic nutrient soil (similar to chemical fertilizer) to provide fertilizer for plants such as flowers and plants, thereby realizing the reuse of garbage and improving the utilization rate of resources.

[0022] As a further structure, the moving knife group 12 includes: a moving knife shaft 121, a plurality of hubs 122 and a plurality of moving blades 123. The plurality of moving blades 123 have different diameter sizes. The moving knife shaft 121 is rotatably supported on the mounting frame 13 and connected to the drive shaft of the driving assembly 11. The plurality of moving blades 123 and the plurality of hubs 122 are stop sleeved on the outer periphery of the moving knife shaft 121, and the plurality of moving blades 123 and the plurality of hubs 122 are spaced apart along the moving knife shaft 121. The moving knife shafts 121 of the two moving knife groups 12 are arranged in parallel on the mounting frame 13. The driving assembly 11 drives the two moving knife shafts 121 to rotate the two moving knife shafts 121 in opposite directions. The moving blade 123 of one of the two moving knife groups 12 is inserted between the two moving blades 123 of the other of the two moving knife groups 12. The diameter of the hub 122 between any two adjacent moving blades 123 is smaller than the diameter of any one of the two adjacent moving blades 123 to ensure that a gap is formed between the two adjacent moving blades 123 for the moving blade 123 of another moving blade assembly 12 to be inserted.

[0023] Specifically, the driving assembly 11 drives the two moving blade shafts 121 to rotate in opposite directions through its driving shaft, thereby driving the moving blades 123 of the two moving blade groups 12 to rotate in opposite directions. The moving blades 123 of the two moving blade groups 12 crush and cut the kitchen waste located at the blade edge of the moving blades 123 when rotating in the opposite direction. Due to the different diameters of the multiple moving blades 123, the outer edges of the multiple moving blades 123 are uneven and not on the same horizontal line. Therefore, there is a height difference between the multiple moving blades 123, so that the crushed materials (i.e., kitchen waste, including hard waste such as large bones) fall on the multiple moving blades 123 in an inclined state, which effectively avoids the phenomenon of material overhead and idling of the moving blades 123 when crushing the materials. When crushing large bones with larger diameters, since the diameter of the large bones is larger and there is a height difference between the moving blades 123, the number of contacts between the large bones and the moving blades 123 is small, so that the bite performance of the multiple moving blades 123 on the large bones is better, thereby reducing the frequency of beating of the large bones and improving the crushing efficiency.

[0024] That is to say, when a large bone falls on a plurality of moving blades 123, it is first engaged and crushed by the moving blades 123 with a larger diameter, and the smaller large bone fragments after being crushed continue to fall down on the moving blades 123 with a smaller diameter and are then engaged and crushed again by the moving blades 123 with a smaller diameter. In this way, the two moving blade groups 12 can crush and grind hard garbage such as large bones, and make the ground garbage particles meet the requirements of the crushed particle size. At the same time, the two moving blade groups 12 are staggered to reduce the number of moving blades 123 that are engaged at the same time, and the required torque is reduced, thereby effectively reducing the motor power required by the kitchen waste crushing device 10.

[0025] Specifically, the material of the moving blade 123 is high-speed steel, which is relatively cheap, saving R&D costs. In addition, the moving blade 123 has a large number of teeth, and the contact frequency between the kitchen waste and the teeth is high during operation, thereby increasing the crushing efficiency.

[0026] As a specific embodiment, the multiple moving blades 123 of the moving blade group 12 have at least three different diameter sizes. The diameter sizes of any three adjacent moving blades 123 of the moving blade group 12 are discontinuously increased or discontinuously decreased. That is to say, among the multiple moving blades 123 on the moving blade shaft 121, any three adjacent moving blades 123 are arranged in a pattern of large, small, and large diameter sizes, or in a pattern of small, large, and small diameter sizes. In this way, it can be ensured that the kitchen waste materials cannot be located above the moving blades 123 in a stable tilted state, further improving the bite performance of the moving blades 123, and further reducing the probability of the kitchen waste materials jumping, thereby improving the crushing efficiency.

[0027] As a specific implementation manner, the power of the kitchen waste crushing device 10 is less than or equal to 2.1 KW.

[0028] As a specific implementation, the diameter of the movable blade 123 is in the range of greater than or equal to 60 mm and less than or equal to 140 mm.

[0029] As a specific implementation, the thickness of the moving blade 123 is in the range of greater than or equal to 4 mm and less than or equal to 10 mm. In this embodiment, the thickness of the moving blade 123 is 6 mm. The stacked thickness of the multiple moving blades 123 and the multiple hubs 122 of the moving knife group 12 along the moving knife shaft 121 is in the range of greater than or equal to 100 mm and less than or equal to 600 mm. The thickness of the hub 122 is slightly greater than the thickness of the moving blade 123. This arrangement makes the moving knife group 12 have a better crushing effect and stronger structural stability.

[0030] Furthermore, the kitchen waste crushing device 10 also includes two stationary knife groups 14. The stationary knife group 14 is used to remove the kitchen waste attached to the moving blades 123 and the hub 122 of the moving knife group 12. Specifically, the stationary knife group 14 is formed with a tooth portion 141. The tooth portion 141 of one of the two stationary knife groups 14 is matched in shape with the multiple moving blades 123 and the multiple hubs 122 of one of the two moving knife groups 12. The tooth portion 141 of the other of the two stationary knife groups 14 is matched in shape with the multiple moving blades 123 and the multiple hubs 122 of the other of the two moving knife groups 12. In this way, when the moving blades 123 and the hub 122 follow the moving knife shaft 121 to crush the kitchen waste materials, the tooth portion 141 can scrape off the residual materials attached to the moving blades 123 and the hub 122, thereby ensuring the normal operation of the moving knife group 12 and keeping the moving blades 123 and the hub 122 clean. At the same time, the teeth 141 of the static knife assembly 14 can also prevent the crushed kitchen waste from splashing upwards.

[0031] As a specific embodiment, the mounting frame 13 includes two side plates 132 and two transverse plates 133. The driving assembly 11 is arranged on the two side plates 132. The moving knife shafts 121 of the two moving knife groups 12 are rotatably supported between the two side plates 132. The two stationary knife groups 14 are respectively installed on the two transverse plates 133. Such a mounting structure is simple and convenient for later disassembly and maintenance. For problematic parts, the corresponding structure can be disassembled and repaired.

[0032] In this embodiment, the kitchen waste crushing device 10 specifically includes two driving components 11, and the two driving components 11 respectively drive the two moving blade shafts 121 to rotate in opposite directions. The two driving components 11 are respectively disposed on the two side plates 132.

[0033] As a specific implementation, the moving knife assembly 12 further includes two deep groove ball bearings 124, two sleeves 125 and a seal 126. The two ends of the moving knife shaft 121 are rotatably supported between the two side plates 132 through the two deep groove ball bearings 124. The two sleeves 125 are respectively sleeved on the moving knife shaft 121 from both sides of the multiple moving blades 123 to axially fix the multiple moving blades 123. The seal 126 is arranged between the sleeve 125 and the deep groove ball bearing 124, so as to seal the sleeve 125 and the deep groove ball bearing 124 at the same time, and prevent the lubricating grease in the sleeve 125 and the deep groove ball bearing 124 from leaking.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
